Re: TF-A Tech Forum regular call

by Olivier Deprez

+ other MLs ________________________________ From: Olivier Deprez Sent: 30 October 2024 11:41 To: tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Subject: TF-A Tech Forum regular call Dear TF-A ML members, As mentioned in https://www.trustedfirmware.org/meetings/tf-a-technical-forum/, trustedfirmware.org hosts regular technical calls on Thursdays. It mentions TF-A although in practise a number of Cortex-A projects beyond TF-A were discussed (refer to prior recordings on this page). Unfortunately this slot hasn't been very active recently. By this email I'm kindly emphasizing this forum is open to the community (and beyond trustedfirmware.org members) and you are welcome to propose topics. Presentations/slides are not strictly necessary, and we can also host informal discussions or session of questions. If you think of a topic, please reach to me and I'll be happy to accommodate. Thanks for your contributions in advance! Regards, Olivier.

Re: Query regarding the test coverage thru tf-a-tests

by Thangaraj, Senthil Nathan

Thank you Joanna and Mark, for your insights and response. I wasn't aware that these tests are running on a Virtual Platform and that's how the coverage is being measured. I'll look into this further, decide how we want to integrate it into our project, and get back to you. I appreciate your help and support here.

Firmware-A v2.10 release code freeze notification

by Olivier Deprez

Hi All, The next release of the Firmware-A bundle of projects tagged v2.10 has an expected code freeze date of Nov, 7th 2023. Refer to the Release Cadence section from TF-A documentation (https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/about…). Closing out the release takes around 6-10 working days after the code freeze. Preparations tasks for v2.10 release should start in coming month. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.: -For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). -For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 in the middle of the patch stack). -Carefully analyze results and fix the change if required, before launching new jobs on the same change. -If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. Thanks & Regards, Olivier.

PSCI patches fail TF-A-tests on 2 platform configs

Maybe there is something wrong with the TF-A patches? Or the platforms tests or configs need to be updated? If you have any clue that would be very helpful! Thanks, Yann

Re: [TF-A] Console scope flags/ console switch state - understanding

by Belsare, Akshay

Hi, Since the discussion is already going on in TF-A list extending it to TF-A Tests list as well. Does TF-A Tests have test cases for console testing in TF-A? more specifically to test the CRASH console?

Standalone python version of generate_test_list.pl?

by Jim Ray

Hello, There's an effort inside of Google to make builds more hermetic across the board. One of the challenges we ran into was supporting the transitive dependencies of generate_test_list.pl, namely XML::LibXML. Since this isn't in the perl standard library, we have to add what amounts to an entire sysroot with a bunch of dependencies just to support this one library. Not impossible (and to be clear, this is the route that we went with), but not ideal either. Another approach that we explored was rewriting generate_test_list.pl in python. XML parsing is in python's standard library and many of our engineers are more familiar with it, so we thought this would be a reasonable choice. We wrote the script, and it seems to work (with some caveats that I'll discuss below). However, we don't want to diverge from upstream, hence why I'm here :). The script is approximately the same length as the original script and supports all of the same features and checking, with one catch. The standard library's XML parsing module doesn't support entity expansion, which is a feature used in many places within TFTF (see, for example, tests-standard.xml). This is done for security reasons and I haven't found a way around it without resorting to xml parsers outside of the standard library (which kinda defeats the purpose). To resolve this, we use xincludes instead, meaning that tests-standard.xml (for example) would have to be rewritten to use the new syntax. For example, tests-standard.xml would look like the following: <document> <xi:include xmlns:xi="http://www.w3.org/2001/XInclude" href="tests-tftf-validation.xml"/> ... rest of includes here... </document> Any thoughts on this? If you're okay with this approach we can put our CL up for review. We also experimented with doing some hand-parsing to support entity expansion and I suspect that there's *some* way to convince entity expansion to occur within the standard library, but wanted to take your temperature on the above changes before pursuing those further. Thanks, Jim
